In color digital jacquard CAD system, the design of the color schemes is both significant and challenging. This paper mainly deals with how to design the jacquard scheme for each color in standard 256 color table with the given 6 different yarns. The features of the color schemes designed in this paper are as follows: 1. Manual operations are avoided in the process of yarn color selection; 2. Engineering difficulties are reduced through lessening the number of the yarns used for the weft; 3. The back side of the jacquard products is no longer in a mess; 4. With only a few changes, the color schemes in this paper can be comfortably applied to the present jacquard machines. In this way, we can not only improve the production efficiency, but also broaden the application market of color digital jacquard technology.
